Warning
Set the parameters strictly according to the scale of external voltage divider, current
shunt and current clamp. Otherwise, the measurement will not reflect the actual signal
and there is danger of electric shock.
Note
The nameplate of the shunt or probe is usually marked with its parameter settings. Refer to the
relevant information of the external sensor if necessary.
Note
The 10 kHz anti-aliasing filter is in the measurement channel. The anti-aliasing filter is
necessary to analyze Fast Fourier Transform (FFT) data correctly and can be used to ensure
that the measurement bandwidth is much less than 1⁄2 sample rate to avoid signal aliasing.
650 Hz low-pass filtering is implemented by a digital filter that helps distinguish the synthesis
frequency and carrier signals of the variable frequency system. Turn on this filter to easily
observe the synthesis frequency of the frequency conversion system.
If measuring a 3-phase system, Fluke recommends that the line filter settings for each channel
in the 3-phase system should be consistent.
The filter is off by default.

Item Description
Vol. Range
Voltage range options:
• Auto: Autorange. The Analyzer automatically selects the voltage
measurement range with the best resolution.
• 10 V
• 100 V
• 1000 V
Vol. Ratio (V/V)
Scale of an external voltage sensor (PT). After setting the scale of the
external voltage sensor correctly, the Analyzer automatically calculates the
actual voltage value of the measured signal based on the voltage scale and
the measured value.
The Vol. Ratio represents the voltage ratio of the external sensor.
For example, when connecting the U1500s high-voltage probe with a voltage
ratio of 4mV/V, which represents a voltage ratio of 4:1000, the Vol.
Ratio (V/V) on the Analyzer should be set to 0.004.
Warning
If the voltage input terminal is not connected to an external
voltage divider in series, set the scale to 1, otherwise the
measured voltage will not be consistent with the actual
voltage, and there is a danger of electric shock.
If the voltage input terminal is connected with an external
voltage divider in series, the actual voltage will be calculated
according to the set scale.
Vol. Line Filter
Voltage signal filter options:
• OFF: No filter is used.
• 650 Hz: Automatically turn on the line filter, and the cutoff frequency is
650 Hz. Use to observe the synthesis frequency signal of the frequency
conversion system.
• 10 kHz: Automatically turn on the line filter, and the cutoff frequency is
10 kHz. Use for anti-aliasing.
Inserting a voltage measurement circuit has a direct impact on the
measurement of voltage and power. When the line filter is turned on, the
measurements do not contain high frequency components. Noise from the
frequency inverter or distorted waveform can be removed.

Cur. Range
Current range options:
• Shunt: Auto, 0.1A, 1A, 10A (when "Ext. Sensor" is not selected)
• Ext. Sensor: Auto, 0.1V, 1V, 10V (when "Ext. Sensor" is selected)
Ext. Sensor
Choose whether to use an external sensor.
When the external sensor is selected/deselected, you must reset the current
range.
If an external sensor is not selected, the current signal is directly connected
to the current channel of 10A, and the current is measured via the internal
shunt.
If an external sensor is selected, the current is measured by connecting the
current signal of external sensor output to the BNC interface.
Cur. Ratio (A/A, V/A)
Scale of an external current sensor (CT). After setting the scale of the
external current sensor correctly, the Analyzer automatically calculates the
actual current value of the measured signal based on the current scale and
the measured value.
The ratio settings are, A/A or V/A.
If the internal shunt is selected, the current scale represents the ratio of the
actual current (A) to the input current (A) on the shunt (that is A/A).
If an external sensor (BNC) is selected, the current ratio represents input
voltage (V) on the BNC port to the ratio of the actual current (A) of the
connected sensor (expressed as mV/A).
For example, when connecting a current sensor probe with an output
sensitivity of 1 mV/A, which represents a 1:1000 ratio, the Cur. Ratio (V/A) on
the Analyzer should be set to 0.001.
Cur. Line Filter
Current signal filter options:
• Off: No current filter is used.
• 650 Hz: Automatically turn on the line filter, and the cutoff frequency is
650 Hz. Use to observe the synthesis frequency signal of the frequency
conversion system.
• 10 kHz: Automatically turn on the line filter, and the cutoff frequency is
10 kHz. Use for anti-aliasing.
Inserting a current measurement circuit has a direct impact on current and
power measurements. When the line filter is turned on, the measurements
do not contain high frequency components. Noise from the frequency
inverter or distorted waveform can be removed.

Table 8. Motor Speed / Torque Channel Configuration
Item Description
Speed
Mode
Speed signal mode options:
• 10V (default): Use for speed sensor for analog voltage output. If the
sensor uses current, frequency or other analog output, it must be
converted to voltage before input.
• A: For encoders with single pulse, only the speed value is measured
and recorded, the direction of rotation is not measured and recorded.
• AB: For encoders with AB double-pulse, both speed value and
direction are measured and recorded.
• ABZ: For ABZ incremental encoder, both speed value and direction are
measured and recorded.
Ratio
Speed sensor ratio.
When Mode is set to 10V, the ratio is in V/rpm, which indicates that how
much voltage (V) it is related to the motor speed (rpm). The formula for the
Analyzer to calculate the actual speed is as follows:
Speed = Voltage/ Ratio
When Mode is set to another option, the unit of the ratio is the number of
pulses per revolution (PPR). The formula for the Analyzer to calculate the
actual speed is as follows:
Speed (rpm) = Pulses per Minute / Ratio

Set the Wiring Selection
To measure the power of various single-phase or three-phase power, different wiring selections are
required, and multiple channel combinations are used. For more information on the connections, see
the Getting Started Manual, shipped with the product or available online.
The Analyzer provides these basic wiring selections:
• 1P2W1M, 1-phase 2-wire 1-meter
• 3P3W2M, 3-phase 3-wire 2-meter
• 3P4W3M, 3-phase 4-wire 3-meter
• 3P3W3M, 3-phase 3-wire 3-meter
Note
In the abbreviation of the wiring selection, letter "P" indicates "Phase", letter "W" indicates
"Wire", letter "M" indicates "Meter", that is power meter (includes one set of voltmeter and
ampmeter).
1P2W1M
Figure 8. 1P2W1M Wiring
For 1P2W1M wiring, connect a voltage measurement channel between the phase line and the zero
line. Connect a current measurement channel in series with the phase line or the zero line (note the
direction) or clamped on the phase line or the zero line with a current sensor.
Torque
Mode: The torque input is -10 V to 10 V the supported input signals must be conditioned to operate
within these limits. If the sensor has a current output this must be converted using a shunt resistor
before applying to the input.
Ratio
Torque sensor ratio. The formula for the Analyzer to calculate the actual
torque is:
Torque = Voltage / Ratio

3P4W3M
Figure 9. 3P4W3M Wiring
For 3P4W3M wiring, 3 voltage measurement channels are respectively connected between each
phase line and the neutral line. 3 current measurement channels are respectively connected in series
with each phase line or clamped on each phase line with a current sensor.
For systems without neutral lines, connect 3 voltage measurement channels between the 3 phase lines
and the common ground line. For a 3P5W system, you can use a wiring group of 3P4W3M to measure
the phase and neutral line. You can select one channel and configure it as 1P2W1M to measure the
parameters between the neutral and ground line (NORMA 6004/6004+ only). If the ground and neutral
lines do not exist, connect the common ends of the 3 channels together and suspend, and the total
power measured is still valid.
For this wiring system:
1. The wiring system has the same impedance characteristics for 3 phases, a balanced measurement
system can be established.
2. The wiring system has a terminal for neutral or ground, the common mode component input to the
instrument is small, which reduces the effect of common mode components on the measurement
results.
3. The phase voltage is directly measured, and the line voltage is calculated by Δ. It is more suitable
for measuring systems of star connections.

3P3W3M
Figure 10. 3P3W3M Wiring
For 3P3W3M wiring, 3 voltage measurement channels are respectively bridged between 2 phase lines.
3 current measurement channels are respectively connected in series with each phase line or clamped
on each phase line with a current sensor.
For this wiring system:
1. This wiring system has the same impedance characteristics for 3 phases, a balanced
measurement system can be established.
2. When measuring the frequency conversion system with the power frequency input, this wiring
system can appropriately eliminate the power frequency component in the frequency conversion
signal, which is conducive to more accurately capturing the conversion frequency.
3. The line voltage is directly measured, and the phase voltage is calculated by Δ. It is more suitable
for measuring systems of Δ connections.
4. The neutral line current can be measured by summing 3 current channel, but the neutral line
voltage cannot be measured. When the neutral line voltage/neutral line current is present, the total
power measured is also inaccurate.

3P3W2M
Figure 11. 3P3W2M Wiring
For 3P3W2M wiring, 1 phase line (C) is used as a common line, 2 voltage measurement channels are
respectively bridged between the other 2 phase lines and this phase line. 2 current measurement
channels are respectively connected in series to the other 2 phase lines, or a current sensor is clamped
on the other 2 phase lines (Also known as two-wattmeter method or Aron method).
For this wiring system:
1. The wiring system can measure 3-phase system with only 2 channels, and 1-2 channels can be
reserved for measuring DC, single-phase AC or 3-phase AC (simultaneous measurement of 2-
channel 3-phase AC is only available for NORMA 6004/6004+).
2. When measuring the frequency conversion system with the power frequency input, this wiring
system can appropriately eliminate the power frequency component in the frequency conversion
signal, which is conducive to more accurately capturing the conversion frequency.
3. The system impedance for the 3 phases is different. The phase voltage and part of the line voltage
are calculated by Δ. In addition, this wiring system cannot measure the voltage and current of the
neutral line. When the neutral line voltage/neutral line current is present, the total power measured
is also inaccurate.

Note
Where the current is measured may have some effect on the measurement results. To mitigate
this effect, consider where the voltage and current are measured. For a signal with high
voltage and low current, the voltage channel should be connected to the side that is closest to
the source, the current channel should be connected in series (or the sensor should be placed)
to the side that is closest to the load (as shown in the wiring diagrams). For a signal with low
voltage and high current, connect the voltage channel to the side that is closest to the load,
and connect the current channel in series (or the sensor should be placed) to the side that is
closest to the source. Please refer to the appendix

Set Sync Source
When the Analyzer measures AC signals, most of the measurements are calculated using the full-cycle
sampling method to reduce the truncation error. In this case, a channel needs to be selected as the
sync source to determine the length of the entire cycle.
Figure 13. Set Sync Source
For each wiring group, you can select a sync source, and the voltage or current of any channel in the
wiring group can be selected as the sync source. In general, the voltage of the power frequency system
is more stable than the current. Fluke recommends using the voltage as the sync source. The voltage
of the frequency conversion system has a large high-frequency component, while the high-frequency
component of the current is relatively small. Therefore, when the current is relatively stable, the current
can be selected as the sync source. However, if the current value is small or it is not stable, then the
voltage should be selected as the sync source.
Zero
The function of zeroing is to reset the current value of the specified channel to calibrate the zero
position of the Analyzer itself and the external sensor. The Analyzer supports zeroing each channel.

A settling time is required during the automatic range switching, and the sampled value during
this time is not accurate, which will cause integral error. Therefore, in order to obtain accurate
integration results, Fluke recommends setting the channel used for integration to manual
range, and the range should cover the instantaneous voltage and current.

How to Make More Accurate Measurements
Measurement Error Caused by the Channel Resistance
By wiring a circuit to match the load, you can minimize the effects of power loss on measurement
accuracy. The wiring of the source and load is discussed in this section.
Figure A1. Connect the Voltage Measurement near the load
Connect the voltage measurement circuit near the load (as shown in
Figure A1). The current
measurement circuit measures the sum of i
Connect the Voltage Measurement near the loadL
and i
V
. i
L
(desired
current) is the current flowing through the load of the circuit under measurement, and i
V
(error current)
is the current flowing through the voltage measurement circuit. Because the current flowing through the
circuit under measurement is i
L
, only i
V
reduces measurement accuracy. The input resistance of the
voltage measurement circuit of the Analyzer is approximately 2 MΩ. If the input voltage is 1000 V, i
V
is
approximately 0.5 mA (1000 V/2 MΩ). Only when the load current i
L
is 0.5 A or more, the effect of i
V
on
the measurement accuracy is 0.1% or less.
Figure A2. Connect the Voltage Measurement near the source
Connect the voltage measurement circuit near the source (as shown in
Figure A2). The voltage
measurement circuit measures the sum of e
L
and e
I
. e
L
(desired voltage) is the load voltage, and e
I
(error voltage) is the voltage drop across the current measurement circuit. The input resistance of the
current measurement circuit of the Analyzer, I Rin is approximately 0.025 Ω. If the input current is 10 A,
the effect of e
I
on the measurement accuracy is approximately 0.25 V (10 A×0.025 Ω). Only when the

load voltage e
L
is 250 V or more, the effect on the measurement accuracy is less than 0.1 %. In
summary, when measuring low voltage and large current, it is recommended to use the wiring method
of the figure above; when measuring high voltage and small current, it is recommended to use the
wiring method of the figure below.
Effects of Leakage Capacitance
Each measurement channel of the Analyzer is isolated from each other. However, these isolated
channels still have a leakage capacitance C
s
relative to the earth, which consists of the distributed
capacitance of the instrument itself, the isolation capacitance of the power adapter, and the anti-
interference capacitance inside the instrument. In general, the test object of the Analyzer has a higher
voltage relative to the earth, and we call this voltage common mode voltage V
com
. The common mode
voltage can generate a current i
cs
through the leakage capacitance C
s
. This current i
cs
will have a
certain impact on the measurement results of the Analyzer.
As shown in
Figure A3, during voltage measurement, the current i
cs
is coupled to the measurement
circuit through R
s+
, R
s-
and R
in
. R
s+
and R
s-
are internal resistances of the power supply under
measurement and R
in
is the test internal resistance of the power analyzer. The effect on the
measurement voltage is: . Because R
in
is larger, internal resistance of
the power supply under measurement R
s-
has the main impact. R
s-
is connected to the common
terminal (black terminal) of the measurement circuit.
Figure A3. Effects of Leakage Current on Voltage Measurement
During current measurement, the current i
cs
flows through the test resistance R
shunt
, and the internal
resistance of the test resistance and the common terminal of the measurement circuit R
s-
and forms a
voltage, that is coupled into the measurement circuit. The effect on the measurement
current: , the voltage drop of i
cs
in R
Shunt
and internal resistance R
s -
can cause measurement errors.

Figure A4. Effects of Leakage Current on Current Measurement
Methods to Reduce the Effect of Leakage Capacitance
1. High frequency components more easily generate current on the leakage capacitance than low
frequency components. When measuring the small current with the built-in current channel, if you
do not pay attention to the high-frequency components of the current, it is recommended to turn on
the 650Hz line filter to effectively reduce the effect of leakage capacitance.
2. Connecting the built-in current channel to terminal N or ground can effectively reduce the effect of
leakage capacitance.
3. Disconnecting the power adapter and using battery only can reduce the effect of leakage
capacitance.
4. When measuring voltage, if the 2 terminals of the voltage source under measurement do not have
the same impedance to the ground, it is recommended to connect the black terminal to the terminal
with lower impedance (to avoid leakage current flowing through the internal resistance of the
voltage source under measurement).
Broadband Measurement
The Analyzer has a bandwidth of up to 500 kHz and a sample rate of 200 kHz. When the measurement
bandwidth is greater than half of the sample rate, aliasing may be caused, the observed waveform is
not the real waveform, and the measured frequency is not the real frequency.
To measure a time-based digital quantity, such as RMS, AC and DC components, the results of the
measurement after aliasing are still accurate. However, note that if the signal frequency is close to or
equal to the sample frequency and its multiples, the measurement results are probably invalid.
If the signal under measurement has a frequency component higher than 100 kHz, and it is not desired
to be measured under aliasing, the line filter of the corresponding channel can be turned on according
to the required bandwidth.
